Your current suspension setup will determine how the sway bar and endlinks improve your ride. IE stock suspension you are going to notice a big difference but its still not going to be exceptional. With a good aftermarket lowered suspension setup you are going to notice a lot more control. It gives the car a sports car feel is how my friend described it after driving my car.
